The present invention relates to fluid operating motors and has for itsprincipal object to provide a fluid operated wheehmounted for rotationupon a suitable supportlng structure and provided with a plurality ofpivoted blades for receiving the force of the fluid for the operation ofthe Wheel and also provided so as to prevent the same from oiieringresistance to the flow of the fluid durlng a predetermined period ofrotation of the wheel. A further object is to provide a fluid operatedwheel of this character adapted to employ the use of either air or wateras the fluid operating agent. A still further object is to provide adevice of this character of a simple and practical construction, whichis strong and durable, efficient and economical in performance,inexpensive to manufacture and otherwise well adapted for the purposesfor which the same is intended. Other objects and advantages reside inthe special construction, combination and arrangement of the variouselements forming the invention as more fully hereinafter described andclaimed, reference being had to the accompanying drawing forming parthereof, wherein like numerals refer to like parts throughout thespecification and in which Figure 1 is a side elevational view of thewheel shown in operative position and with its supporting base shown insection,

Figure 2 is a vertical sectional view through the wheel and supporttherefor, and

Figure 3 is a perspective View of one of the blades.

Referring now to the drawing in detail, wherein for the purpose ofillustration I have shown a preferred embodiment of my invention, thenumeral 5 designates a supporting base having a vertically extendingrecess formed therein within which to receive the lower end 6 of a wheelsupporting standard 7 At the upper end of the standard 7 is arranged abearing bracket 8 within which a shaft 9 is journalled for rotation. Theshaft is horizontally disposed and formed of pair of shaft sectionshaving heads 10 for attaching at opposite sides of a pair of hub shellsections 11 combining to form a hollow sphere.

5 The spherical sections 11 are disposed at the opposite sides of aspherical hub 12 and with their walls in spaced relation from the hubasclearly shown in Figure 2 of the drawing. The hub 12 is'formed at thecenter of a disk wheel 13 and to the opposite faces of which is arrangeda series of blades 14, preferably in pairs, immediately opposite eachother. Each of the blades are carried on a rockshaft 15 extendingradially of the hub with their inner ends inserted in openings formed inthe shell sectionsand arcuately shaped as .at16 for fitting between theshell and the hub so as to permit pivotal movement of the shafts. Theouter ends of the shafts are journalled in eyes 17- carried on the facesof the disk. The standard 7 is of a substantially bifurcated formationas clearly shown in F igure 2 of the drawing whereby to permit the wheelto rotate between the furcations thereof. Each of the shafts 15 carryinner and ,outer laterally extending pins 18 and 19 respectively,arranged adjacent the inner and outer ends of the shafts. Extendingforwardly and rearwardly from the standard is an outer arcuate guide 20composed of a pair of spaced parallel guide members disposedat oppositesides of the wheel and between which the wheel rim is adapted to pass.

The upper ends of the sections of the standard 7 are also provided withan inner arouate guide 20' with their inner edges also disposed inspaced relation and providing space for the passage of the shaftstherebetween. Upon the rotation of the wheel the pins at the inner endsof the shafts will engage the 35 guide 20 and the pins at the outer endsof the shafts will engage the guides 20 whereby to rotate the shafts andturn the blades 14 edgewise. As soon as the shafts leave the oppositeend of the guides the force of the fluid striking the blades will causethe same to open for receiving the full driving force of the fluid. Thelower end of the standard 7 is rotatably supported in the base 5 and atone side of the standard and extending parallel with the wheel is arudder 21 adapted to keep the wheel headed into the air or water so thatthe blades will respond to the force thereof. It will thus be apparentthat during a portion of the rotation of the wheelsubstantially half ofthe blades will be feathered so as to offer no resistance to the waterwhile the remaining blades will be open to receive the force of thefluid and thus cause the rotation of the wheel. It is obvious that theinvention is susceptible of various changes and modifications withoutdeparting from the spirit thereof, or the scope of the appended claims,and I accordingly claim as my own all such forms of the invention towhich I am entitled.

I claim 1. A fluid motor comprising a base, a standard rotatablysupported therein and having its upper end bifurcated, a shaftjournalled for rotation at the upper portion of the standard, a pair ofcooperating hub shell sections attached to the shaft, a wheel having aspherical hub disposed within the shell for rotation upon the shaft axisand adapted to travel between the furcations of the standard, aplurality of shafts carried by the wheel and extending radially fromsaid hub, a blade carried by each of said shafts, a pin extendinglaterally from each blade shaft and stationary means engageable withsaid pins whereby to feather said blades during a pre-determined periodof rotation of the wheel.

2. A fluid motor comprising a base, a standard rotatably supportedtherein and having its upper end bifurcated, a shaft journalled forrotation at the upper portion of the stand ard, a pair of cooperatinghub shell sections attached to the shaft, a wheel having a spherical hubdisposed within the shell for rotation upon the shaft axis and adaptedto travel between the furcations of the standard, said shell sectionsbeing in spaced relation from the hub, a plurality of shafts carried bythe wheel and extending radially with respect to the hub, said shaftshaving their inner ends curved and disposed between the hub and theshell to provide a rotatable support for the shafts, a blade carried byeach of the shafts, a pin extending laterally from each blade shaft andstationary means engageable with said pins whereby to feather saidblades during a predetermined period of rotation of the wheel.

In testimony whereof I affix my signature.
